I love the gridfinity system started by Zack Freedman and the design idea of easy accessibility and of displaying the stuff that is stored, rather than store it away. With my Gridfinity Ikea Samla adapter (https://bit.ly/GridfinitySamlaAdapter11l) I added an easy way of transporting more than a few boxes which I felt was lacking.

But when stacking several bins on top of each other it can be a bit tedious to access the lower bins in the Ikea Samla box. So I made a tray that can be placed on top of Gridfinity bins like normal bins and should be sturdy enough to lift it out easily.

It is the same size as the baseplate on the bottom of the 11l Ikea Samla box (39x28x14 cm) with a 5x7 grid. And it only reduces the capacity of an 11l box by 1 3U high divider bin. So you can stack 4 3U high divider bins and the tray in an 11l Ikea Samla box. The handles are designed for optimal usage when stacking 2 3U high divider bins on the bottom and 2 3U high divider bins on the very top.

Or you can just use it as a regular tray for moving your Gridfinity bins. You can then use any of the x*5 sized modular baseplates (https://bit.ly/GridfinityModularBaseplates) to attach the handles to (will not snap in to the top of other bins if you use it like that).

New - Small and Big Handle

There is now a small and a big handle available.

• The small handle fits perfectly in the Samla 11l boxes.
• The big handle is designed to be used with the Samla 22l boxes. The small handle can also be used with the Samla 22l box, but only on the top.

What do you need to print

• You need to print 2x the Handle_Small.stl or Handle_Big.stl
• If you have the possibility print 1x the TrayPlate_5x7.stl (requires at least a 300x250mm print bed). This will give you the best stability and best experience.
• Or you can print 2x the TrayPlate_3x5.stl and 1x the TrayPlate_1x5.stl and attach them together with screws.

Assembly

• Use 4 m3x12 button head cap screws (BHCS) and 4 m3 hex nuts to attach the two handles to the 5x7 tray plate (2 screws per handle are enough, but you can use more if you want)
• If you decided for the two 3x5 and one 1x5 tray plates attach them together using 10 m3x8 screws (BHCS) and 10 m3 hex nuts first (same way as for the bottom grid for the Ikea Samla box - see here: https://bit.ly/GridfinitySamlaAdapter11l)

Attribution

I designed the handles of the tray myself.

I marked the model as remix because the tray plate is based on my modular gridfinity baseplates (https://www.printables.com/model/360046-gridfinity-modular-baseplates). The baseplates are now stackable. The original baseplates have a flat bottom and are desiged to be placed on flat surfaces. These baseplates cannot only be securely stacked upon another, but also be securely stacked on bins. It allows layered storage of gridfinity bins combined with easy accessibility. This is reached by the bottom of the baseplates being modeled after the Gridfinity system and based on the specification available at https://gridfinity.xyz/specification/ which is shared unter the licence https://creativecommons.org/licenses/by-nc-sa/4.0
